First, make the problem 5n + -37 = 3n + -55. Then add -3n to each side. So you now have 2n + -37 = -55. Then add 37 to both sides, and then you end up with 2n = -18. Next, divide each side by two, like this: 2/2n = -18/2. So your final answer is n = -9.

5n-37=3n-55
+37 +37
5n=3n-18
-3n -3n
2n= -18
2n/2= 1 -18/2= -9
1. -37 is in the way of getting n by itself,so add 37 on both side.
2. -55+37= -18
3. so, 5n =3n-18
4.subtract 3n on both sides, so that the problem is simplified.
5. 5n-3n=2n
6. idvide 2n by itself, that equals 1 and by -18
7. n= -9

5n-37=3n-55
1. You want to isolate the variable so you should SUBTRACT 3n from both sides and ADD 37 to both sides.
2. You should get 2n=-18
3. Divide -18 by 2
4. The answer is -9

5n-37=3n-55
move the same things to the same sides
take 3n from both sides
2n-37 = -55
now add 37 to both sides
2n = -18
divide by 2
n = -9

5n-37=3n-55
add 37 to each side
(5n-37)+37=(3n-55)+37
5n=3n-18
subtract 3n from each side
(5n)-3n=(3n-18)-3n
2n= -18
divide both sides by 2
2n/2= -18/2
n= -9
